 * Hi,
 * When I select a category using its id I would like to automatically select all
   its subcategories.
 * Is this possible?
 * Thanks

 * Hi there,
 * Yes, the plugin should be able to list all entries that belong to a given category(
   even if they’re under a subcategory).

 * If I have category A and category B where B is a subcategory of A and for the
   category id I select only A it will not show posts which have category B even
   though it is a subcategory of A

 * Ah, you’re correct. My mistake. It’s been a while since I last used the category
   filter, and didn’t check the code before replying.
 * Indeed, the plugin will list only those posts that belong to a given category
   ID. To list posts under a subcategory, you’d also have to pass its ID to the 
   filter. Lame, I know, but it’s this way by design to avoid putting a heavier 
   load on the database by doing extra queries just to retrieve all subcategories
   IDs from a given category.
